▼ Install a PCIe Riser Into PCIe Slots 3 and 4
Note – The PCIe riser in slots 3 and 4 is different than the PCIe risers in slots 1 and
2. Do not attempt to install a PCIe riser from slot 1 or 2 into PCIe slots 3 and 4 and
vice versa.
1. Retrieve the PCIe riser and any PCIe cards attached to it.
2. Reconnect the SAS cable(s) to the internal host bus adapter card [1].
Be sure to connect the SAS cable for storage drives 0 through 3 (HDDs 0-3) to the
connector that is farthest from the riser in which the HBA card is installed;
otherwise, the server will incorrectly identify the storage drives when it is
powered on.
3. Raise the green-tabbed release lever on the PCIe riser to the open (up) position,
and then gently press the riser into the motherboard connector until it is seated
[2].
